I would suggest an online business plan software. With a web-based tool, it's much easier to develop your plan and financials with your team. We use iplanner.net (see the product card below), but there are, of course, more options on the web. You may want to check out WickedStart.com, and eFactor.com. They offer a lot of tools for small business owners.
